Miyabi Kaizen 8-inch Chef’s Knife Review ( Medium, Black with Red Accent)

Where it’s made

miyabi kaizen chef knife is handcrafted by japanese knife smiths in seki, japan. Miyabi is a part of famous german knife maker zwilling . But miyabi knives are made in japan with the combination of japanese traditional knife-making techniques and modern german technology. Hardly any knife manufacturer can hold a candle to Miyabi when it comes to fit and finish. 

Blade material (VG-10 super steel)

Blade core of miyabi kaizen knife is made with VG-10 super steel which is known as the gold standard of knife making. VG-10 cutting core is wrapped on either side with 32 layers of stainless steel. Those layers protecting the core against rust, pitting, and things like that. That’s total of 65 layers gives it a beautiful damascus look. 

VG-10 is famous among the Japanese knife makers because of its qualities like hardness, edge retention, rust resistance, etc. It’s a high carbon stainless steel alloy of carbon, chromium, molybdenum, vanadium, and cobalt. Carbon increases hardness, chromium makes it rust-resistant. Other components provide strength, durability and flexibility. 

Blade Design

Miyabi kaizen chef knife has a beautiful flower damascus pattern of 65 layers of stainless steel. You can clearly see that weavy damascus pattern on the whole body of the blade. It looks like matt finish on the blade. 

It has an authentic thin Japanese blade profile. So, it has a slight curve from both the bottom and top parts. The spine is nicely grounded for a comfortable pinch grip. And finally, you will find the logo of Miyabi on the blade.

Sharpness and edge

Miyabi kaizen 8-inch chef’s knife has an insanely sharp hand-honed 9.5 to 12 degree cutting edge. It’s almost half what other knife manufacturers, even japanese manufacturer grind their knives to. It’s really very sharp and thin knife which provides effortless and precious cutting. 

This sharpness comes from the traditional japanese 3 steps Honbazuke technique. In the first two steps, knives are grounded and sharpened using vertical and horizontal rotating stones. Then they are mirror polished on leather belts. This process has been used for hundreds of years for the ultimate sharpness of samurai swords. 

In addition, this knife is a dual bevel knife. It means it has same sharpness from both of the side, unlike traditional Japanese knife. And this makes it usable for both left and right-handed persons. 


The hardness of any knife mainly depends on blade material, forging and other processes. This high carbon VG-10 steel and ice hardening ensure the hardness of miyabi kaizen with rockwell hardness of 60. 

Miyabi uses CRYODUR ice-hardening process to enhance blade properties and make it hard but not brittle. In this complex process at first, the blade is heated up in a vacuum-sealed oven and cooled down to room temperature. Then it is cooled down to very low freezing temperature. This continuous heating and cooling process develop steel structure and increase hardness.

This tough hardness ensures edge retention for a long. A hard blade retains its edge for a longer period than any soft blade. Moreover, the cryodur process ensures to not make it brittle with hard.

Handle material

Miyabi kaizen knife’s handle is made with black linen Micarta. Micarta is a composite material of resin, canvas, linen, paper, burlap etc. It has a beautiful grain structure with wood-like texture. This handle material makes the handle extremely resistant to moisture and water. So, the handle provides a comfortable slipless grip and lasts for a long. 

Micarta handle may feel a little bit heavier than the normal wooden handle. But the micarta handle retains its feel for a long time. 

Handle Design

The handle features a traditional japanese D shape look. It has a round shape with a slight D curve at the right side so it fills your palm in very nicely when you hold it. As the curve on right side is not so aggressive you can hold it with your left hand with comfort. It feels like a sand finish on the handle that makes it slipless.

The most beautiful feature on the handle is the mosaic pin going through the center. It is about 15 to 20 little pieces of brass, copper, and stainless steel that have been individually pressed into the handle as a final finish touch. It also contributes to handling durability.

There is an elegant-looking logo craved steel cap at the end part of the handle. It contributes to the balance and weight distribution of miyabi kaizen chef’s knife. You will also find two red accent spacers that add more beauty to the elegant black handle. 


Blade of miyabi kaizen knives goes through the whole handle so it is a full tang knife. Full tang knives are always preferred over half tang knives. Because full-tang knives are usually more durable and resistant than half-tang. It also adds better weight distribution and balance to the knife. 

Weight and balance 

The total weight of miyabi kaizen is 11.2 ounces. That’s pretty lightweight compare to other knives of its size. So it will not create pressure on your wrist even after long use. Moreover, it will work like a part of your hand while cutting, chopping or slicing. 

Full tang, steel end cap all these things are added to ensures proper weight distribution through the knife. You will get proper balance while working with this knife and get used to it quickly.Its balance is almost at the center point. 


The total length of miyabi kaizen 8 inches is 14.75 inches. So, the blade is of 8-inch length which is most preferred for a wide range of work. And the handle length is more than 6.5 inches. It will fit both is large or small hand. This blade has a thickness of 1 inch that is pretty thin.

Clean and maintenance 

Like all japanese or miyabi knives kaizen prefers handwash. Washing it with a dishwasher may cause the edge and create chip that will make your knife valueless. So, after every use just wash it with water. If needed use soap and wash with your hand using water. 

Don’t forget to dry the knife after washing. Keeping it without drying can damage it. So, put it in an open place before storing so that water vaporizes and the blade dries out properly. 

As miyabi kaizen doesn’t come with any sheath you have to use any wooden knife block or sheath it stores it. Never put it in a drawer without a sheath that may damage the edge. Don’t use a magnetic knife keeper.

How the knife will feel in your hand

A knife may be beautiful or made with quality material but the most important thing is the feeling that you will get while taking it in hand. 

The D shape handle will fit in your hand properly while working. Moreover, as the handle doesn’t absorb moisture, you will feel a slipless grip. 

The razor-sharp edge will provide an effortless and smooth cut, so it will feel like a  part of your hand while using. Moreover, as the knife has pretty lightweight it doesn’t create pressure on the wrist. You will also get a comfortable pinch grip as the spine is well-grounded .
